Description

Technical Field

[0001] This utility model relates to the field of rejection device technology, specifically a lightweight rejection device support. Background Technology

[0002] In industrial production and various product processing processes, rejectors are widely used as key equipment to ensure product quality and improve production efficiency. There are many types of rejectors. For example, in the food, chemical, and pharmaceutical industries, weighing rejectors are commonly used to accurately measure product weight and reject products that exceed or fall below the standard weight. In the field of electronic component manufacturing, visual inspection rejectors, utilizing advanced image recognition technology, can quickly and accurately identify and reject products with appearance defects or that do not meet size specifications. There are also air-blowing rejectors that use airflow to blow defective products off the production line.

[0003] Due to the wide variety of rejectors, the corresponding mounting brackets also exhibit diverse designs. In practical applications, rejectors typically operate in complex environments, often accompanied by strong vibrations and frequent shaking. To ensure stable operation and accurate product rejection under these unstable conditions, existing rejector brackets are often designed with stability in mind. Generally, these brackets employ a large and heavy structural design, increasing their weight and base size to enhance stability in vibration environments. However, large and heavy brackets not only increase transportation costs and difficulties but also cause numerous inconveniences for workers during equipment installation, commissioning, and subsequent maintenance, impacting work efficiency.

[0004] In order to reduce transportation costs and improve the convenience of equipment installation, commissioning and maintenance while ensuring stable operation of the rejector, we propose a lightweight rejector bracket. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a lightweight rejector bracket, including a mounting cylinder 1, a sliding cover 2 fixedly connected to the top of the mounting cylinder 1, a sliding rod 3 slidably connected to the inner wall of the sliding cover 2, a first connecting rod 25 rotatably mounted on the sliding rod 3, a connecting block 4 fixedly sleeved on the outside of the first connecting rod 25, a mounting plate 5 provided on the top of the connecting block 4, a cylinder 6 fixedly mounted on the mounting plate 5, a mounting frame 7 fixedly connected to the output end of the cylinder 6, two sets of support frames 14 hinged on the mounting cylinder 1, a folding component for easy folding of the support frames 14 mounted on the mounting cylinder 1, a fixing component for fixing the sliding rod 3 mounted on the sliding cover 2, and an adjustment component for adjusting the angle of the connecting block 4 mounted on the sliding rod 3;

[0030] The folding assembly includes two sets of movable blocks 21. The movable blocks 21 are slidably connected to the inner wall of the mounting cylinder 1. An insert plate 35 is fixedly connected to the movable blocks 21. The insert plate 35 slides through the mounting cylinder 1. The support frame 14 has a slot that matches the insert plate 35. The mounting cylinder 1 is equipped with a moving mechanism that drives the movable blocks 21 to move. The sliding cover 2 is equipped with a support mechanism that supports the support frame 14.

[0031] In use, the rejector is mounted on the mounting frame 7. The cylinder 6 drives the mounting frame 7 to reciprocate, thus rejecting and classifying products. The position of the sliding rod 3 can be adjusted and fixed using a fixing component, thereby adjusting the height of the mounting frame 7. The angle of the connecting block 4 can be adjusted using an adjusting component, thereby adjusting the angle of the mounting frame 7, ensuring it is positioned appropriately on the production line for optimal performance. The moving mechanism moves the moving block 21, causing the insert plate 35 to disengage from the slot, allowing the support frame 14 to rotate; inserting the insert plate 35 into the slot fixes the support frame 14. This facilitates the folding and unfolding of the support frame 14. Folding the support frame 14 during transport reduces its size, lowering transportation costs and complexity. Unfolding the support frame 14 during installation, combined with the support mechanism, forms a stable base, ensuring stability during use. This achieves stable operation of the rejector while reducing transportation costs and improving the ease of installation, debugging, and maintenance.

[0032] The moving mechanism includes a connecting frame 22, which slides through the mounting cylinder 1. Two sets of L-shaped plates 32 are fixedly connected to the bottom of the connecting frame 22. Two sets of protrusions 34 are fixedly connected to the side of the L-shaped plate 32 near the moving block 21. The moving block 21 has a groove 36 that matches the protrusions 34. The groove 36 is inclined and the protrusions 34 are slidably connected to the groove 36. A spring 33 is fixedly connected to the bottom of the L-shaped plate 32. The bottom of the spring 33 is fixedly connected to the bottom of the inner cavity of the mounting cylinder 1.

[0033] Press down on the connecting bracket 22 to move the L-shaped plate 32 down. The two sets of moving blocks 21 move closer together through the cooperation of the protrusion 34 and the groove 36, which can drive the insert plate 35 out of the slot. After rotating the support frame 14 to the appropriate position, release the connecting bracket 22. Under the action of the spring 33, the L-shaped plate 32 rises and resets, so that the insert plate 35 is inserted into the slot again, fixing the position of the support frame 14.

[0034] The support mechanism includes several sets of sliding blocks 11, which are slidably connected to the outer wall of the sliding cover 2. A support rod 12 is hinged to the sliding block 11, and the end of the support rod 12 away from the sliding block 11 is hinged to the support frame 14.

[0035] The support frame 14 is equipped with a placement box 13, which is a hollow box. Weights, iron blocks, and other heavy objects can be placed in the placement box 13 to increase the overall weight of the support frame 14 and make the support more stable.

[0036] The fixing assembly includes two sets of connecting covers 10, which are fixedly connected to the sliding cover 2. A sliding plate 27 is slidably connected to the inner wall of the connecting cover 10. A plug 19 is fixedly connected to the side of the sliding plate 27 near the sliding cover 2. The plug 19 slides through the sliding cover 2. Several sets of insertion holes 9 that match the plug 19 are opened on the sliding rod 3. A sliding mechanism that drives the sliding plate 27 to slide is installed on the connecting cover 10.

[0037] The sliding mechanism includes a second drive rod 37, which is rotatably installed between two sets of connecting covers 10. Both ends of the second drive rod 37 are fixedly connected to screws 23, which rotatably pass through the connecting cover 10. Threaded sleeves 20 are fixedly connected to the sides of the two sets of sliding plates 27 that are close to each other, and the threaded sleeves 20 are threadedly connected to the screws 23.

[0038] Manually rotating the second drive rod 37 drives the screw 23 to rotate. Under the action of the threaded sleeve 20, the sliding plates 27 move closer together, causing the insert block 19 to disengage from the insertion hole 9. This allows the position of the sliding rod 3 to be adjusted, thereby adjusting the height of the mounting bracket 7. After adjusting to the appropriate position, rotate the second drive rod 37 in the opposite direction to insert the insert block 19 into the insertion hole 9, thus fixing the position of the sliding rod 3.

[0039] The adjustment assembly includes several sets of first rotating rods 18, which are rotatably mounted on sliding rods 3. A drive gear 28 is fixedly sleeved on the outside of the first rotating rod 18. Several sets of rotating gears 26 that match the drive gear 28 are fixedly sleeved on the outside of the first connecting rod 25. The rotating gears 26 mesh with the drive gear 28. A mounting cover 17 is fixedly connected between the two sets of sliding rods 3. A rotating mechanism that drives the first rotating rod 18 to rotate is mounted on the mounting cover 17.

[0040] The rotating mechanism includes a first drive rod 38, which rotatably passes through the mounting cover 17. Both ends of the first drive rod 38 are fixedly connected to drive bevel gears 31. A turbine 29 is fixedly sleeved on the outside of the first rotating rod 18. Several sets of worm gears 24 that match the turbine 29 are rotatably connected to the inner wall of the mounting cover 17. The worm gears 24 mesh with the turbine 29. A rotating bevel gear 30 is fixedly sleeved on the outside of the worm gears 24. The rotating bevel gear 30 meshes with the drive bevel gear 31.

[0041] Manually rotating the first drive rod 38 drives the drive bevel gear 31 to rotate. Rotating the bevel gear 30 drives the worm gear 24 to rotate, which in turn drives the turbine 29 to rotate, causing the first rotating rod 18 to rotate. With the cooperation of the drive gear 28 and the rotating gear 26, the first connecting rod 25 rotates, which in turn drives the connecting block 4 to rotate, thereby adjusting the angle of the connecting block 4. The self-locking mechanism between the worm gear 24 and the turbine 29 keeps the connecting block 4 stable.

[0042] The mounting bracket 7 is provided with several sets of reinforcing rods 8 and has several sets of through holes 15. The reinforcing rods 8 can increase the overall strength of the mounting bracket 7, thereby reducing the thickness of the mounting bracket 7. The through holes 15 further reduce the overall weight of the mounting bracket 7, thereby reducing the impact force on the cylinder 6 during reciprocating motion, extending its service life, and reducing the failure rate.

[0043] Both the sliding rod 3 and the support rod 12 are hollow. The mounting cylinder 1, sliding cover 2, sliding rod 3, support rod 12, and support frame 14 are all made of aluminum alloy. This reduces the overall weight while ensuring support strength.

[0044] Working Principle: When this lightweight rejector bracket is in operation, the rejector is first installed on the mounting frame 7. The mounting frame 7 is driven by the cylinder 6 to reciprocate, completing the rejection and sorting of products. If the height of the mounting frame 7 needs to be adjusted, the second drive rod 37 is manually rotated, driving the screw 23 to rotate. Under the action of the threaded sleeve 20, the two sets of sliding plates 27 move closer or further apart, causing the insert block 19 to disengage from or insert into the insertion hole 9 on the sliding rod 3, thereby adjusting and fixing the position of the sliding rod 3. When the angle of the mounting frame 7 needs to be adjusted, the first drive rod 38 is rotated. The drive bevel gears 31 at both ends drive the rotating bevel gear 30, which in turn causes the worm gear 24 to rotate. The worm gear 29 meshing with it rotates accordingly, driving the first rotating rod 18 to rotate. Through the meshing of the drive gear 28 and the rotating gear 26, the first connecting rod 25 rotates, realizing the adjustment of the angle of the connecting block 4. The self-locking characteristics of the worm gear 24 and the worm gear 29 ensure that the connecting block 4 remains stable.

[0045] In the operation of the support frame 14, pressing down on the connecting frame 22 causes the L-shaped plate 32 to move downwards. Utilizing the sliding engagement between the protrusion 34 and the inclined groove 36 on the moving block 21, the two sets of moving blocks 21 move closer together, causing the insert plate 35 to disengage from the slot of the support frame 14, at which point the support frame 14 can be folded. After releasing the connecting frame 22, the L-shaped plate 32 rises back to its original position under the action of the spring 33, and the insert plate 35 re-inserts into the slot to fix the support frame 14. When the support frame 14 is unfolded, the support rod 12 hinged to the sliding block 11 provides support, enhancing stability. Furthermore, the reinforcing rod 8 on the mounting frame 7 increases structural strength, and the through hole 15 reduces weight. The sliding rod 3 and support rod 12 are hollow, and components such as the mounting cylinder 1 and sliding cover 2 are made of aluminum alloy, effectively reducing overall weight while ensuring support strength. The placement box 13 can also hold heavy objects to further increase the stability of the support frame 14, thereby ensuring stable operation of the rejector while reducing transportation costs and improving the convenience of equipment installation, debugging, and maintenance.
